This paper is concerned with the investigation of the effects of a magnetoplasma layer on the radia· tion properties of an infinite axial slot on a circular cylinder when a finite magnetostatic field is in the axial direction. Formulas have been obtained for the field s e ve rywhere around the cylinder and for any thi c kness of the magnetoplasma. The solution is simplified by a first orde r approximation , valid only for s mall thicknesses of the laye r. For a s mall " koa" the harmonic series converges we ll and is used for numerical co mputations . For large "koa" the converge nce is improved by applying the Watson's transformation . Dis tortion, attenuation, and asymmetry of the radiation pa tte rn are shown as a function of the s trength of the magne tos tatic fi e ld . It is found that the reve rsa l of the ori entation of the magnetos tati c fi eld produces a s hift of the patt e rn to a mirror.image position.
